RAZOR-BLADE SHARPENER.

scription of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to a razor blade sharpener.

An object of the invention resides in the provision of a machine by means of which a plurality of razor blades may be sharpened simultaneously and which is so constructed that any one of the blades may be removed and replaced while the machine is going at full speed. r

A further object of theinvention resides in so constructing the machine that the razor blades will be given amovement longitudinally of the sharpening rolls.

A further object of the invention resides in so constructing the machine that its operation will be automatic. r v

\Vith these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claims. ii

' 'Fig. 10 is a section on line 1010 of Fig. 6; and I l V Fig. 11 is a perspective view of one of the holder clamps.

Referring to the drawing wherein like throughout the several views;

In the embodiment of the invention shown Specification of Letters Patent.

mounted in each of the in the drawing I have illustrated a base l which is supported upon suitable legs 2.

Mounted upon thisbase '1 is a pair of up warclly extending standards 3 between which sharpening rolls .4: are mounted, the trunnions 5 on one end of which extend through the adjacent standard 3 secured thereto.

In orderthat these rolls 4 may .be ro tated so that the adjacent rolls will move-in the opposite directions, I have provided a shaft 7 which is rotatably mounted in certain of. the legs 2 and has a drive pulley 8 on one end thereof which is adapted to. be connected to any suitable source of motion. Secured to the other end of the shaft 7 is a pulley 9; A belt 10 passes over this pulley 9 and thence'dircctly to and over the uppermost pulley 6. The belt then-passes around shown in Fig; 6 of the drawing.

Formed on the standards 3 are ears 11 on which arms 12 are pivotally mounted, the said'arms being held in position by rods13 as clearly shown in Fig. 6 of'the drawing.

each of the succeeding oulleys 6 in a manner and have pulleys 6 Patented Mar. 20, 191 '7. Application filed September 13, 1915. Serial No. 50,460.

Connecting the upper ends of. the standards 3 is a cross bar 14 on the ends of which arms 15 are pivotally mounted. The arms-12 and 15 are connected together by vertical bars 16 at one side of the device. The ends of the arms are bifurcated to form ears 17 between j which bearing blocks 18 are pivotally mounted on pins 19. Crossbars 20 are rotatably mounted in these bearing blocks-18. Depending from the ends of the'arm 15. at the opposite side of the machine to that on. which the bars 16 are located are bars21' V which are connected to the crosslbars 20by means of links 22, whichlinks are rigidly secured to 'the'cross bars and pivotally s'ecurediat 23 to the bars 21. Thus the cross bars 20 may move transversely of the map 7 chlne upon the movement of the arms 12 and' i 15 .or they maybe rockedintheba-ring blocks 18 for a purpose which will later appear. l

j Secured to each ofthe cross vbars20'is plurality of clamping members 24, each of" which is provided at one ofits ends with a pair of spaced resilient fingers25 in which housings 26 are formed. Theother endof each of the members is provided with resilient fingers 27. The number of these clamping members may 7 the length of the bars 20/ Removably belimited only by.

clamping members 7 2a is a blade holder 28 which is provided with pins 29 adapted to be engaged by the fingers 27 and pins 30 adapted to be located in the housings 26 in the fingers 25. The

blade holder is provided with a socket 31 in which the back of the blade is adapted to be engaged and held in position by a thumb screw 32. When the blades are in place in the holders and the holders are in position upon the clamping members, the blades will extend between the rolls 4:.

In order that the blades may be moved so that they will engage the rolls which are located beneath them, for a predetermined interval, and then the rolls which are located above them, I have provided a shaft 33 which is mounted in suitable bearings 3e upon the base 1. Secured to this shaft is a drive pulley 35 over which a belt 36 extends which belt also extends over a pulley 37 upon the shaft 7. Secured to the shaft 33 is a sleeve 38 having a cam groove 39 therein. Pivotally mounted upon a block 40 is a bell crank lever ll having a pin 42 on the end of one arm thereof, which pin extends into the cam groove 39. Pivotally secured to the other end of the lever n is a link 43 which is connected at its upper end to an arm 44. This arm 44: is connected to the adjacent cross bar 20. Thus as the sleeve 38 rotates the lever 11 will be actuated and the cross bars 20, through the bars 21, links 22 and arms 15, will be moved about their pivots so that the blades will be shifted upwardly and downwardly into contact with the adjacent rolls.

In order that the blades may be moved longitudinally of the rolls while they are in contact therewith, I have extended one of the bars 21 downwardly and have mounted a roller 4L5 on the lower end thereof which roller rides in the cam groove 39 in the sleeve 38 and moves the arms 12 about their pivots. This movement of the arms will cause the blades to travel backwardly and forwardly across the sharpening rolls.

It will thus be seen that I have provided a machine for sharpening razor blades in which the blades will be moved longitudinally of the rolls and in contact therewith while the rolls are rotating to sharpen the blades. Furthermore, I have so constructed the device that any one of the blades may be removed and replaced without necessitating the stopping of the machine.

While I have illustrated and described a particular embodiment of my invention, it has merely been for the sake of convenience and I do not wish to be limited to that particular embodiment as it is obvious that numerous changes may be made within the scope of the appended claims.

IVh-at I claim is 1. In a razor sharpening machine, the combination with a plurality of sharpening rolls arranged in superposed relation, of means for supporting a plurality of razor blades in contact with said rolls, means for moving the blades alternately into contact with the adjacent rolls, means for moving the blades longitudinally of the rolls and common means for actuating the two last mentioned means.

2. In a razor sharpening machine, the combination with a plurality of sharpening rolls arranged in superposed relation, of means for supporting a. plurality of razor blades so that they will extend between the rolls, means for shifting the blades alternately into contact with the adjacent upper and lower rolls and means for moving the blades longitudinally of the rolls while they are in contact therewith.

3. In a razor sharpening machine, the combination with a base, of a pair of standards extending upwardly therefrom, horizontally arranged sharpening rolls mounted between said standards in superposed spaced relation, horizontally movable arms mounted on said standards, bars connecting said arms, said bars being mounted on horizontal pivots, means on the bars for supporting a plurality of razor blades in contact with the said rolls, means for moving the arms pivotally and means for simultaneously moving the bars pivotally.

4.. In a razor sharpening machine, the combination with a pair of standards, of sharpening rolls mounted therebetween, arms pivotally mounted on the standards and adapted to swing in horizontal planes, bars rotatably mounted on the arms and adapted to swing in vertical planes at right angles to the planes in which the arms swing, clamping members mounted upon the said bars and razor blade holders detachably mounted on said clamping members.

5. In a razor blade sharpener, the combination with a pair of standards having sharpening rolls mounted thereon, of a frame mounted upon said standards, blade holders mounted upon said frame, means for moving the frame in a horizontal plane and means for simultaneously moving the blade holders in vertical planes at right angles to the planes of movement of the frame.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
